Is it possible for me to have output that go to the $stdout go through a  
method instead? ie:

Have stuff go through this:

def write\_to(str)  
@socket.send(str, 0)  
end

?

You can assign any object that responds to #write to $stdout.

In this case IO#reopen seems more appropriate IMHO (if it works with  
Sockets, which I did not verify). It’s faster (no Ruby code needed)  
and will also work for sub processes.

Kind regards
